Reversible window



T all whom z't mag oonce1%:-

Be it known that* I, WARREN E. Summ, a citizen of the 'Um'ted Staates, residing in the eity and oounty of San Francisco, and State of Caliform'a, have invented a new and useful Improvement in a Reversible Window, of whichthefollowing is a specification. My invention relates to improvenients in v0 reversible windows whereiu sliding guides and carrier armS normally enclosed within the sash and casement of a window operate to guide and frictionallmhold said windoW in any osition when one side of the window Y 5 is moved outwardly along an arcuate path to the opposite Side of the ease1nent he primary object of my inve ntion is to provide an improved reversible window. Another obj ect of my invention is to pro- 0 v1de improved means for enelosing'the guidand carrying elements o1: a. reversible window' within the sash and casement of a window. A further object of my inveni sion is to 5 provmle improved frictional connections adapted to' hold a window in a partially opened position.

A still further object of my invention is to prov1de an improved window adapted to be mounted within'a casement without altering the framing of said casement.

I accomplish these and other objects by means of the improved device disclosed in -I the girawings forming a Part of the present speelfication wherein like characters of reference are used to designate similar parts throughout said specification and drawing, and in which Fig. 1 is a perspeetive view of my improved window. 7 Fig. 2 is a vertical section through the Window disclosed in Fig. 1, disclosing the manner in which the window may be moved ax1s. Fig. 3 is a vertical s'ection similar to Fig. 2 disclosing a Window adapted fo'r movement about a vertical axis. Fig. 4 -iS an enlarged broken detail disclosing the track and guide shoe at one side of the window, Fig. 5 is a broken horizontal secj;ion haken along the line 5-5 of F1g. 4.

Fig. 6 is a broken vertical section tak en along the line 6-6 of Fig. 4. v

F ig. 7 is anenlarged broken detail partly in seotion disclosing my improved carrien arm and friction bearin Referring to the. drawmgs the numerail 1 is lised inggeneral to designate a window sash mounted within a casement 2; A traek 3 is nailed 01' otherwise s eoured -tothe casement 2 upon o poSite sides 01 upon top and bottojn as disc -0Sed in Figs. 2 and 3 of the drawings. The tracks are stamped fr0m Sheet metalor formed from any other suit= able material and are provided each with an L shaped flange 4 adapted to engage an Oppositely faced L shaped flange 6 formed upon a shoe 7 arran'ged to slidably engage casemerit within.a recess formed by a sh0ul dered facing member 14 as best disclosed in F ig. 5 of the drawing. The sash 1 is shoul dered as at 16 to provide a recess to receive the shoe 7 and sash strip 12, the strip 12 being ofl'set as at 17 to space the shoe 7 away from the sash and permit the shoulder 16 to elear the shoe when the window i s' moved as hereinafter described. In this manner the-track and shoe are enclosed by the casement and sash thereby reducing exposure to 1;he weather and improving the ap earance of the finished window.

8arrier arms 18 are pivotally secured at the sash 1 adjacenti one end thereof to jamb plates 19 secured to Y the casement 2 at the extreme ends of the tracks 3 remote from' the shoes 7 when the Window is in the closed osition, by means of suitable rivets 21. A was'her 22 of' brass 01' other non-corroding material is provided between each arm 18 and its plat-e 19 t0 prevent the members from rusting together in a manner preventing relative movementf. of the same about the rivet 21 as an a'xizs. The other end "of each carrier arm 18 1s pivotally secured to the sash 1 b y means o:f a friction bearing23 comprising a bear1ng block 24 drilled and countersunk to receive one end of a rivet 26 of brass or other noncorroding material. The'blocks 24 are provided with a plurality of lugs 27 adapted to engage recesses formed to match therewith in sash plates 28 screwed or otherwise secured to the Sash 1 at points slightly in advance of the center on the shouldered sides of the sash. The carrier arm 18 is drilled to receive the rivet 26 and is pro-- vided with a countersunk portion 29. A noncorrodin washer 31 is provided between the sas plate 28 and the arm 18 for the purpose previously explained. The carrier arm 18 normally lies within the recess at the ed e of the sash edge when the window is c osed and is enclosed between the sash am]. the frame by the shoulder 16.

The edge of the sash 1 between the shoes 7 is beveled as at 30 topermit rotative movement of the sash about the rivets 8 securing the shoes to the sash. The slots 9 am provided in-the shoes 7 to permit reversal of said shoe for use either upon the right 01' left side of the sash. The shoes 7 are riveted to the sash strips 12 before securing the same to the sash 1. When it is desired to changxe a shoe from a right band to a left band shoe, th shoe is turned throu h 180 about the rivet 8 and moved longitu inally until the rivet 8 engages the slot 9 at the opposite end thereof. In this manner, shoes 7 may be made idei1tical end adapted for" use on -either side of the sash after assembly.

In operation my window fits neatly against the facing members 14 providing a window of the usual appearance and effectually shutting out air currents, rainand other elements. Whei1 it is desired to open the window,. theend 0r side of the sash remote from the shoes 7 is forced outwardly from the casement' against the frictional resistance of the bearin s, the sash being carried by the arms 18 an moving pivotally about the bearings 23 as best d1selosed in Fig. 2 of the drawings. The shoes 7 slide along the traoks 3 and hold the end of the sash to which they are secured in -alignment within the casement. The sliding movement of.the shoes 7 compensates for the lowering of the pivot bearings 23 as the arm 18 is swung outwardly ab0ut the pivot 21. As the bearings 23 are looated slightly beyond the center of the sasli, the free ehd.of the sash may be moved outwamdly'along an arcuate path until the opposite end of the casement 1s reached, the shoes being moved at the same time to the end of the tracks 3 as shown in dotted lines in Fig. 2. Inthis manner, the

window may be reversed to bring the outen side of the window toward the interior to facilitate eleaning and the like.

The operation of a window mounted for movement about a vertica l axisis identical With that of a window mounted to move about a horizontal axis. In Fig. 3 I ha.ve

illustrated such a window, the lower track 3 being provided with an outwardly extending portion 32 t0 prevent we ar on the sill 33 of the window as the window sash is moved thereialong.

The rivets 8, 21 and 26 about which pivotal movement oocurs are made sufliciently rigid to cause friction for holding the window in any desired position without the us e of}grops or other locking members.

aving thus described my inventio n what I claim as new and desire to secure by Let ters Patent is:

1. In a reversible window,the oombination With a casement havirig recesses and a sash movable in said oasement, of a pair of tracks secured to the casement within said recesses; a pair of interchangeable guide shoes pivotally mounted upon one end of the sash' tion with acasement having recesses and a sash movable in said oasement, of a pair of tracks having L shaped flanges formed thereon secured to the ca*sement within the recesses; a pair of interchangeable guide shoes pivotally mounted upon one end of the sash and having L-shaped flanges faoed oPpositely to and slidably engaging the L- .shaped flanges of the traoks within the reoesses to guide said end within -the casement, said shoes having longitudinally disposed slots t0 permit increased vertical movement of the sash and to permit said shoes to be reversed for application upon either side of the sash; and .Carrier arms pivotally counected to the Oasenient .and the sash to guide the free end of the sash along an arcuate path when moved outwardly from the casement.

3. In a mounting for reversible windows of the charaetcr described, a guide shoe provided with a longitudinal slot; a sash platze adapted for :ittachment to a window sash; and a rivet'slidably and pivotally' conneeting said sash plate with said shoe throgh said Slot, to permit said shoe tobe reversed about said riv etfor use upon ei ther side of the sash.
